Jammin’ Jars Slot Details & Wager Limits

Reels/Paylines: 8×8 Grid, Cluster Pays

Stakes Range: 20p to £100 per spin

Max Win: 20,000 x stake per spin

The Jammin’ Jars slot takes place on an 8×8 grid and uses a Cluster Pays mechanic. To form a win, you need to land a cluster of 5 or more matching symbols to create a winner. A cluster is defined as 5 or more matching symbols touching vertically and/or horizontally.

After a winning spin, the successful symbols are removed from play and new ones drop in and replace them. A new payout calculation is then made. The collapses continue as long as a new winning combination is created. Helping to create them is the jam jar symbol which is the wild.

If the wild forms part of a winning cluster, it moves to an adjacent position prior to the next symbol collapse. All jam jars on display are held in place when a collapse occurs. The jam jar wilds also come with multipliers. These increase by 1x every time they form part of a winning combination. They drop off the reels when no new winner is landed.

You can play Jammin’ Jars from 20p to £100 per spin which caters to all bankrolls. There is an Autoplay function (located next to the main spin button) where you can choose from 10 to 100 spins. You also have the option to set a loss limit (up to 100 x stake) or a single win limit (again up to 100 x stake). In the Settings area, you can opt for the Turbo Mode function as well as remove all sounds, music and sound effects.

Jammin’ Jars is a very high variance slot. With great risk, there’s normally great rewards. That’s certainly the case here as you can win up to 20,000 x your stake on each spin.

That said, there’s not much in the way of variety but it’s the simplicity, big win potential and high RTP which makes Jammin’ Jars such a lethal fruit cocktail. It’s an all or nothing slot game though so you need patience and luck.

As a result, Jammin Jars’ has achieved cult status and is played regular by slot streamers in the hope of landing the big possible payouts. One of the most popular free play slots in the UK, it’s played just as much today as when it was first released.

Due to it’s success, Push Gaming released the Jammin’ Jars 2 slot. With a lower RTP of 96.4%, it comes with more bonus features and bigger max wins of 50,000 x bet.

Jammin’ Jars FAQs

The Jammin’ Jars RTP is 96.83%. The average is around the 96% mark so this is substantially higher. However, this is a highly volatile offering though so it’s all or nothing in terms of payouts.

The maximum payout is 20,000 x your total stake per spin. This is won when you get big multipliers in the base game or free spins. In the latter, the Jam Jar wild multiplier values can only increase which increases your chances of winning big.

Jammin’ Jars has a $1 where you’ll get 6 free spins. However, the multipliers from the base game are carried through with each cascade increasing the multiplier. The good news is that multipliers can only increase which can lead to 20,000 x stake wins on each free spin.

Yes. There’s a $1 available here at Online-Slot.co.uk. You can play the popular slot on desktop, mobile or tablet devices that use iOS, Android or Windows technology.
